Can Getopt::Long accommodate variable option names?

Question

I am writing a script that can do something like:

script-name --resource1=xxx --resource2=xxx

But this can go up to 50+. Is there a way to make GetOpt accept dynamic option names?

What about auto-generating the options list for Getopt::Long like example below? Since the list of options will be likely pretty long, using Getopt::ArgvFile allow you to supply configuration file with options instead of specifying them on command-line.

use Getopt::Long;
use Getopt::ArgvFile;
use Data::Dump;

my @n = (1 .. 10);    # how many resources allowed
my %opts = (
    port                  => ':i',
    http_version          => ':s',
    invert_string         => ':s',
    ssl                   => '',
    expect                => ':s',
    string                => ':s',
    post_data             => ':s',
    max_age               => ':i',
    content_type          => ':s',
    regex                 => ':s',
    eregi                 => ':s',
    invert_regex          => '',
    authorization         => ':s',
    useragent             => ':s',
    pagesize              => ':s',
    expected_content_type => ':s',
    verify_xml            => '',
    rc                    => ':i',
    hostheader            => ':s',
    cookie                => ':s',
    encoding              => ':s',
    max_redirects         => ':i',
    onredirect_follow     => ':i',
    yca_cert              => ':s',
);

my %args = ();
GetOptions(\%args,
    map {
        my $i = $_;
        ( "resource$i:s", map { "resource${i}_$_$opts{$_}" } keys %opts )
    } @n
) or die;

dd \%args;
